DUMPlNG-CART.

SPECIFICATION forming part of Letters Patent No.414,947, dated November12, 1889.

Application filed August 16, 1889. Serial No. 321,034. (No model.)

To all whom t may concern/.-

Beit known that I, FRANCIS THOMAS LYNCH, of the city of Baltimore andState of Maryland, have invented certain Improvements in DumpingCoal-Carts, of which the following is a specification.

This invention relates to certain improvements in that class ofdumping-carts in which the body thereof is elevated from the shafts inthe dumping operation; and it consists in y certain combinations ofparts, as hereinafter fully described and claimed. A

In the description of the said invent-ion which follows reference ismade to the accompanying drawings, forming a part hereof, and in which-Figure l is an exterior side elevation of the principal parts 4of theimproved dumpingcart, and Fig. 2 a plan of the same with certainunessential portions removed.

In the said drawings, A represents the shafts and B the body, of thecart. The body B, when in its lowest position, rests on the shafts A andis contin ed sidewise between the slotted standards D,which are erectedon the shafts. Studs E on the sides of the body enter the slots a of thestandards and are connected to chains b, which pass over sheaves c inthe slots of the standards and down to grooved winding-drums F. Thesewinding-drumsare on a shaft G, running across and under the shafts A andconfined in suitable bearingboxes. (Not shown.)

To the outer ends of the shaft G are secured toothed pinions I-I, iugear with toothed sectors I on a shaft J, supported under the shafts inlike manner to the shaft G, before alluded to. These sectors are eachprovided with a socket e, into which a lever K is fastened. The upperends of the levers K are attached by means of chains e to windingdrums Lon the shaft M, and the windingdrums are provided with ratchet-teeth fand 'pawls g, to hold the winding-drums in any position in which theymay be placed. One of vthe shafts M is adapted to receive a crankhandle,whereby it may be turned by hand to hoist the body, as will hereinafterappear.

N is a slotted link pivoted to one of the shafts A at 7i, and c' is astud which projects from the side of the body and through the slot ofthe link. The end of the stud is threaded and provided with a threadedhandle 7'.

The body B is furnished with the usual chute for conducting the coal asdischarged to some desired point; but this chute is not shown, asl it isno part of my invention.

The body of the cart is elevated by winding the chain e on theWinding-drums by means of the crank-handle before alluded to. In windingthe chain the levers are drawn back, and in this movement the toothedsectors effect the rotation. of the pinions H. These pinions, being onthe shaft carrying the winding-drums L, the chains e are wound thereonand the body of the cart lifted.

The tilting of the body into a position similar to that indicated by itsdotted delineation in Fig. l is effected by tightening the stud t' bymeans of the handle j, which has the effect of preventing furtherelevation vof the body at that point. may begin with the elevation ofthe body or at any time during the elevating operation.

I claim as my invention- Ina dumping coal-cart, the shafts A, havingslotted standards, and sheaves in the slots of the standards and neartheir top, combined with the body having studs which enter the slots ot'the standards, a shaft secured under the shafts, carrying toothedpinions and winding-drums, another shaft carrying toothed sectors ingear with the said pinions and also sockets, levers which project fromthe sockets, a third shaft carrying windingdrums and ratchet-teeth, andchains to connect the last-named winding-drums with the upper ends ofthe levers, substantially as and for the purpose specified.
